Reduced-complexity decoding of LT codes over noisy channels
Iqbal Hussain, Ming Bo Xiao, Lars Kildehoj Rasmussen · 2013
We propose an adaptive decoding scheme for Luby Transform (LT) codes over noisy channels which exhibits lower complexity as compared to the conventional LT decoder. The corresponding modified degree distributions have been derived for the low-complexity LT decoder. The complexity and performance comparison demonstrate that the decoding complexity can be reduced with negligible degradation in bit error rate performance.
